Prospects for CO2 Capture and Storage
What is CO2 capture & storage?
What are the costs?
How does the cost-effectiveness of CCS compare to other emission reduction options?
What will it take to bring CO2 capture and storage to market?

Energy Technology Scenarios
What is CO2 capture & storage?
Capturing CO2 from the gas streams emitted during electricity production, industrial processes or fuel processing
Transporting the captured CO2 by pipeline or in tankers
Storing CO2 underground in deep saline aquifers, depleted oil and gas reservoirs or unminable coal seams

Energy Technology Scenarios
Capture – Technology Status
CO2 capture is a proven technology
It reduces emissions by 85-95%
But its energy efficiency can be further improved and cost must be reduced
This requires integrated power plant and CO2 capture designs
Most of these advanced designs are not yet proven on a commercial scale
Examples: new chemical absorbents, oxyfueling, hydrogen combined cycles, IGCC, USCSC, chemical looping, fuel cells

-50% to +30%
Nuclear power allowed to grow -40%
No IGCC for synfuel cogeneration -30%
Cheaper renewables because of investment policies & technology learning
-50%
Additional electricity savings (10% more) -15%
GDP growth 2.2% to 3.2% (basis: 2.8%) -15% to +15%

RD&D gaps
More proof of storage needed
CO2 capture demonstration needed
0.5-1 bln per demonstration plant
Present spending 100 MUSD/yr
A fivefold increase of RD&D needed

Energy Technology Scenarios
Long-term policy framework andincentives
In addition to the acceleration of RD&D funding, countries should create a level-playing field for CCS alongside other climate change mitigation technologies. This includes ensuring that various climate change mitigation instruments, including market-oriented trading schemes, are adapted to include CCS.

Conclusions
CCS can play a key role in addressing global warmingmainly through coal plants in coal-rich regionsbut also some natural gas opportunities
Carbon incentives are needed, but also:Proven technologyAcceptable storage
